A poor ratio of Oxygen will cause incomplete combustion and the consequent deposit of carbon.

ICE Princess25 [194]

Answer:

Raster Image Correlation Spectroscopy (RICS) is a novel new technique for measuring molecular dynamics and confocal fluorescence imaging concentrations. RICS technique extracts information on molecular dynamics and concentrations of live cell images taken in commercial confocal systems

Explanation:

RICS analysis must be performed on images acquired through raster scanning. Laser scanning microscopes generate images by measuring the fluorescence intensity in one area of a pixel at a time (a 'pixel' in this context does not have the same definition as a pixel in computer graphics, but refers to a measurement of localized intensity). The value of a pixel is obtained by illuminating a region of the sample with the focal volume of a laser beam and measuring the intensity of the fluorescence emitted. The laser beam moves to a new location and a new pixel is recorded. Each pixel can be considered to correspond to a region of the sample, with its width (called pixel size) defined by the distance the beam moves between measurements. This means that the size of a pixel is separate and independent from the size of the focal volume of the laser beam.

What is the final volume?

zaharov [31]

Answer:

Option A. 9.4 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 8 L

Initial temperature (T₁) = 293 K

Final temperature (T₂) = 343 K

Final volume (V₂) =?

V₁ / T₁ = V₂ / T₂

8 / 293 = V₂ / 343

Cross multiply

293 × V₂ = 8 × 343

293 × V₂ = 2744

Divide both side by 293

V₂ = 2744 / 293

V₂ = 9.4 L

Therefore, the final volume of the gas is 9.4 L

Define diffusion. Is it faster in summer or winter season?

Basile [38]

Diffusion is the process of a substance spreading out to evenly fill its container or environment. Kinetic energy of particles of matter increases with an increase in temperature. More the kinetic energy in the particles, more is the rate of diffusion. so diffusion is faster in the summer!

hope this helps!

calcium is obtained industrially by electrolysis of molten cacl2 and is used in aluminum alloys. how many coulombs are needed to

Vinvika [58]

It takes 107 minutes 22 seconds and 96500 coulombs of charge produce 20.2 g of calcium.

The balanced equation for the reaction is,

$CaCl _{2} \:→ \: Ca ^{ 2 + } + 2Cl {}^{ - }$

The half-reaction of calcium is,

$Ca ^{2 + } + 2e ^{ - } → \: Ca$

Mass of calcium = 20.2 g

The molecular mass of calcium = 40 u.

The number of moles calcium are,

$Number \: of \: moles = \frac{mass}{molecular \: mass}$

$= \frac{20.2}{40}$

$= 0.5 \: moles$

One mole of Calcium is produced by 2 moles of electrons.

So, 0.5 moles of Calcium produce,

$= 0.5 \times 2$

$= 1 \: mole \: of \: electron$

The charge required to produce 202 g of calcium is,

$= 1 \:F$

$= 1 \times 96500 \: C$

$= 96500 \: C$

Current = 15 A

The time taken to produce 20.2 g of calcium is,

$I = \frac{Q}{T}$

$T = \frac{96500}{15}$

$= 6433.3 \: s$

$= 107 \: minutes \: 22 \: seconds$

Therefore, 96500 columns of charge are required to produce 20.2 grams of calcium. And it takes 107 minutes and 22 seconds.

Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 at

Ugo [173]

Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K.

The Van der Waals equation, also known as the Van der Waals equation of state, is an equation of state used in chemistry and thermodynamics that extends the ideal gas law to take into account the effects of molecular interaction as well as the finite size of the molecules in a gas.

We may build a new equation that better reflects real gas behavior by modifying the ideal gas law to include corrections for interparticle attractions and particle volumes. The van der Waals equation can be used to determine a gas's properties under less-than-ideal circumstances.
